No incision, no visible scar, no nasal packing at all. Many patients are back at the hotel the very next day.
The pituitary gland sits at the base of the brain, just beneath the optic chiasm, and controls the body's hormone balance — thyroid, adrenal, growth, and reproductive function all pass through it. A pituitary tumor (adenoma) is almost always a benign growth of the gland itself, not a cancer. Tumors are classified by size — microadenomas (under 10mm) and macroadenomas (10mm or larger) — and by function: some produce excess hormone ("functioning"), while others are hormonally silent ("non-functioning") and cause problems only through their size.
Many non-functioning tumors are found incidentally, on imaging done for an unrelated reason, or once they grow large enough to press on the optic chiasm and affect vision.
Symptoms depend on whether the tumor is hormonally active and on its size. Common presentations include:
MRI with a dedicated pituitary protocol — often called a dynamic pituitary MRI — is the standard imaging test. A full hormone panel — prolactin, growth hormone/IGF-1, cortisol/ACTH, thyroid, and reproductive hormones — determines whether the tumor is functioning. Formal visual field testing is added whenever the tumor approaches considerable dimensions.
Not every pituitary tumor requires surgery. The right approach depends on whether it produces excess hormone, its size, and whether it is affecting vision.
Surgery (endoscopic, transsphenoidal) is the right first step for the great majority of pituitary tumors — non-functioning macroadenomas, any tumor affecting vision, hormone-active tumors other than prolactinoma, and — regardless of size — any tumor showing hemorrhage or signs of prior bleeding. For most patients, surgery is the starting point, not a later resort.
Prolactinoma is the one type usually treated differently: some small prolactinomas respond well to medical treatment first, with a dopamine agonist shrinking the tumor and normalizing prolactin without an operation. Surgery is still used when a prolactinoma is very large or doesn't respond to medication.
Observation has a narrow role — only for some small, non-functioning tumors with no effect on vision or hormone levels, followed with periodic MRI scans rather than treated outright.
Explore how the decision is made for a pituitary tumor, and what a typical surgical journey looks like.
Dynamic pituitary MRI identifies the tumor; a full hormone panel and, where relevant, formal visual field testing complete the picture.
Endocrinology and ophthalmology weigh in alongside neurosurgery to determine function, visual impact, and the best path forward.
From here, the recommended path depends on the clinical picture. Tap a profile to see the reasoning:
Whichever path is taken, hormone levels are monitored closely afterward, with endocrinology follow-up and imaging on a set schedule to confirm the tumor remains controlled.
Dynamic pituitary MRI, a full hormone panel, endocrine consultation, and visual field assessment.
The tumor is removed endoscopically through the nose — no incision, no nasal packing — followed by post-op imaging to confirm the result.
If there's no CSF leak at the surgery, anterior pituitary hormone levels are checked and the patient is discharged the same day — straight to the hotel.
Hormone levels are rechecked and an endocrine consultation confirms everything is stable.
If all is normal, the patient can fly home — staying around 10 days after surgery makes for a more comfortable flight.
